ALBERT H. FIELD, OF PROVIDENCE, RHODE ISLAND.

PRINTERS METAL SLUG.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application file'i January 27,1903. Serial No. 140,760.

To all whom it may concern.-

Be it known that I, ALBERT H. FIELD, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Printers Metal Slug, of which thefollowing is a specification.

My invention relates to improvements in printers metal slugs commonlyused for the spacing of lines of type; and the objects of myimprovements are, first, to utilize the slugs as a tie-up for type-formsby so binding the types that they are in no danger of becomingdisarranged or pied, (doing away with the old-fashioned method of usingstring or twine for the purpose,) and, secondly, for the blanking out oftype-formsthat is, by a combination of slugs to form a hollow spacewhere no type is used in composition, the improvements in no way toaifect their utility as slugs as they are now used in all printeries. Iattain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 indicates a perspective view of improvedslug. Fig. 2 shows the staple used. Fig. 3 represents a type-formsecured by slugs as intended in my invention, also showing slugs as usedfor blanking out and their common use in spacing lines of type; Fig. 4,two ends of slugs engaged as used for the purpose of tying up atype-form.

Similar letters refer to similar parts throughout the several views.

Referring more particularly to the drawings, Fig. 1 indicates theimproved printers metal slug, with a knob or boss (1 at one end and slotor gain 6 at the other. A multiple of bosses or gains may be used forthe purposes of dovetailing; but one boss and one gain, as shown, ispreferable. Slugs are interchangeable.

The letters 0 indicate mortises at even distances from the ends andrunning perpendicularly through the width of slug for reception of pinsor staples.

The staple d, as in Fig. 2, is used for securing ends of slugs for thepurpose of a tieup and is formed of three bends or kinks at angles offorty-five degrees, the top portion being lateral to the ends of pinswhich bind in mortises of slugs and so fashioned that when slugs aresnugly bound around the typeform the ends of slugs will be separated bya nonpareil or six points, type measure, each way, as Fig. 4. This is toallow for a take-up or squeeze when form is being locked up in chase atthe imposing-stone. When form is securely locked in chase, staples d arethen removed and replaced only after form has been to press and justprevious to unlocking for distribution.

In the matter of tying up, the compositor may start with two slugs inthe galley and set his type in or against them, or he may set in theusual way and place slugs around form at finish, spacing out with leadsto cause slugs to bind sufficiently.

Regarding a blank space in form, it is only necessary to learn thenumber of ems each way, and slugs may be assembled almost as quickly ascompositor can lift them. Where the blank space is a large one, a numberof squares or oblongs may be formed to fill same, and greater securitywill result. The improved piece of metal is still a slug and may be usedfor spacing of lines and all other purposes the compositor has hithertofound for them.

Slugs may be made of any suitable metal consistent with strength,preferably brass or steel.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

As a new article of manufacture, a tie-up for printers type-forms,consisting of metal slugs, having a boss at one end and a gain at theother, and also having mortises at equal distances from the ends,running perpendicularly through the width of slugs, for receivingstaples formed of three bends or kinks at angles of fort -five degrees,the top portion being lateral to the side portions of the staples; allsubstantially as set forth and used for the purpose specified.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
